Females located by Todd Stout on Murdock Mountain and also on July 27, 2008, Jack Harry, Les Davis and I located  females past mm 27 along the Mirror Lake Highway, Duchesne County, Utah.  Females were returned to the same location after we obtained these eggs.
N. 40.40.881, W. 110.55.165
Elevation 10,349 feet

Ova
Four  females oviposited 160 ova on an unknown Vaccinium  within a couple of days.  The eggs  hatched after four days.

Larva
We put the larvae on Salix exigua (Brush Willow)  which they refused to feed on, and all but 50 died.  We  moved the surviving 50 larvae to Diamondleaf Willow, Salix planifolia  which was growing at the same location in which the females were flying.  The larvae fed on that plant just fine.  I kept them under light 24x7, nevertheless they all hibernated except one.

Pupa
A pupa formed August 27, 2008 and female butterfly hatched after six days.

Host
The females oviposited on an unknown vaccinium and the larvae fed on  D. Willow - Salix planifolia.  After hibernation, they fed on Salix exigua.  For photos of the host plant used, click on
